IMPROVEMENT IN EARTH-AUGERS.

Specification forming part of Letters Patent No. 155,939, dated October13, 1874; application filed August 10, 1874.

To all whom it may concern:

Be it known that I, ROBERT J. GARDNER, of Carlisle, in the county ofPrairie and State of Arkansas, haveinvented a new and Improved Well-Auger; and I do hereby declare that the following is a full, clear, andexact description ofthe same, reference being had to the accompanyingdrawing forming a part of this specification, in Which- Figure 1 is asectional elevation; Eig. 2, a horizontal section.

The invention will first be fully described, and then pointed out in theclaim.

A represents a rotary shaft, which has the bit a, bottom B, and twoopposite cutters, O O. This bottom is radially slotted at b bin the samediametrical line, and beneath each is located one of the inclinedcutters G, With edge c turned up above the bottom. D is an inverted cupor top closed cylinder, which slides centrally and loosely on the shaftA, fitting down on the bottom B, and between the edges c c. E is a bandor ring, having radial arms e, made fast to shaft A by keys c1 c1, andsuitable Washers c2.

The operation is as follows: As the auger is screwed into the earth thecutters G C take off a shaving or thin slice of soil andtranst'er it upthrough and upon the bottom B. This continues until the top-closedcylinder is filled and rises on the shaft to the ring E. As no more dirtcan pass through the bottom the operation ceases, and the operator drawsthe auger out for emptying.

This auger has been practically applied to bore from four to thirty-sixinch es, and is found to do its work with great neatness and efficiency,as Well as with much less than the usual expenditure of labor. Y

Having thus described my invention, what I claim as new is- Anearth-auger, consisting of the end-bitted shaft A, having radiallyslotted bottom B, and edge-turned knives O O, the sliding topcloscdcylinder D, and the fast ring E, all constructed and arrangedsubstantially as and for the purpose specified.
